Objectives: Deletion of gene in mice has been linked to progressive hearing loss and degeneration of cochlear cells. Cisplatin, an antitumor drug, can cause various side effects, including ototoxicity. The aim of this study was to investigate the effects of on cisplatin-induced hearing impairment in mice and to explore the possible mechanism.
Methods: Two-week-old mice and mice were treated with two doses of cisplatin, with a 3-day recovery period in between. ABR (auditory evoked brain stem response) thresholds were measured and cochlear pathology was observed at 3 weeks of age.
Results: Both and mice showed hearing loss under the effect of cisplatin, but the impairment was more severe in mice. Further experiments showed that the percentages of outer hair cell (OHC) and spiral ganglion neuron (SGN) loss were significantly higher in cisplatin-treated mice compared to mice. Additionally, knockdown of in HEI-OC1 cells worsened cisplatin-induced cell apoptosis.
Conclusion: FSCN2 mediates reduction of CDDP induced ototoxicity by inhibiting cell apoptosis.

Endothelial dysfunction, characterized by a decline in endothelial physiological functions, is a significant aspect of cardiovascular aging, contributing notably to arterial stiffness, atherosclerosis, and hypertension. Transient receptor potential channel V4 (TRPV4), a key member of Ca-permeable channels, plays a crucial role in maintaining vascular functions. However, the role and mechanisms of TRPV4 in aging-related endothelial dysfunction remain incompletely understood.

Atopic dermatitis (AD) is a chronic inflammatory skin disease, characterized by an impaired epidermal barrier and immunological alterations. The activity of the cytoprotective NRF2 transcription factor is reduced in the epidermis of AD patients. To determine the functional relevance of this deficiency, we used mice lacking fibroblast growth factor receptors 1 and 2 in keratinocytes (K5-R1/R2 mice), which exhibit several AD-like symptoms.

Neovascular age-related macular degeneration (nAMD), characterized by choroidal neovascularization (CNV), is one of the leading causes of severe visual impairment and irreversible vision loss around the world. Subretinal fibrosis (SRF) contributes to the incomplete response to anti-vascular endothelial growth factor (VEGF) treatment and is one of the main reasons for long-term poor visual outcomes in nAMD. Reducing SRF is urgently needed in the anti-VEGF era.

Background: Smooth muscle cells (SMCs) of the proximal thoracic aorta are derived from second heart field (SHF) and cardiac neural crest lineages. Recent studies, both in vitro and in vivo, have implied relevance of lineage-specific SMC functions in the pathophysiology of thoracic aortic diseases; however, whether 2 lineage-derived SMCs have any predisposed transcriptional differences in the control aorta remains unexplored.
Methods: Single-cell RNA sequencing and single-nucleus assay for transposase-accessible chromatin sequencing were performed on isolated cells from the aortic root and ascending aortas of 14-week-old SHF-traced () and cardiac neural crest-traced () male mice.
